IMPROVED FILING lllIAGlEIIIlE.V

A. G. BURTON AND H. W. COVERT, OF ROCHESTER, NEW YORK. Letters PatentNo. 59,741, dated November 20,' 1866.

SPEGIFCATION- TO ALL WHOM IT MAY GONCERN: l

Be it known, that we, A. G. BUR'roN and H. W. Covnar, of Rochester, inthe county of Monroe, and Stai of New York, have invented certain newand useful improvements in tiling machines; and we do hereby declai thatthe followingis a fuli and exact description thereof, reference beinghad to the accompanying drawing making part `of this specification- Fig.1 is-a plan of our improved machine.

Like letters of reference indicate corresponding parte in allthefigures.

It is' the object of our improvement to produce a machine that shall beadapted to the general purpose filing, by the application of power,thereby obviating, in a-great degree, 'the laborious hard work nownec'cssar especially where heavy work is to be dispatched.

AS represented in the drawings, A indicates a frame of suitableconstruction, having longitudinal slots, a or equivalent, in the ends,for the connection and adjustment of the carriage frame B, and thesustaining tab or equivalent general support,v C, for the reception ofthe articles to be filed. In ,order to connect these par we prefer touse ball and socket joints, of substantially the following construction:

The socket D is made of two parts b b, which receive the ball E, andclamp together to hold it xedly any position, by means of ianges c c,having tighteningVA screws d d. The socket is also provided with a befiange f, connecting with the slots a, by means of a nut and bolt g, orequivalent, by which means it is adjust forward or back. l

The carriage frame and table or support are respectively secured to thetops of the balls E E, -'asshown fig. 2.

The carriage frame consists simply of a horizontal flange h, forattaching to the -top of the ball, an uprig bed or back z', and lugs lck, on opposite sides, for holding the carriage in place and allowing itsreciprocatio To the top of the carriage frame is secured aishaft G, withwhich are connected a pulley Z, to receive belt for applying power tothe machine, and a cam rm, substantially of the form indicated in fig.2, for acting the carriage to produce its reciprocations. Any equivalentmeans of producing the reciprocations of carriage-such, for instance, asa pitman and crank--may be employed; but we prefer, the cam for reasonshe inafter set forth. i i

The carriage is substantially of the -form indicated in figs. 2 and 4,having a body H, which rests agai the back of the frame, and flanges nn, that run in the lugs'k c, to hold the carriage in place. Where the cm, is employed, we prefer to employ a friction wheel o, on top. Thesides of the carriage are provided u vertical grooves p p, orequivalent,to receive tongues q qof clamps I I, which hold the iile K in placemeans of set screws rr. These clamps may be adjusted higher or lower atpleasure.

The side of the carriage is provided with a. pin or stop s, fitting inany one of a set of adjusting holes This pin or stop, striking ashoulder k, of the frame, will gauge the length 'of the stroke of thecarriage. reaction of the carriage against the driving cam, when thelatter is used, maybe produced by any suitablespr arrangement. Bythismode of driving the iilene'arly all the time is employed in moving itforward or do ward to perform its work, while its return movementoccupies scarcely any of the time. Thus either timi power, or both, areeconomized, as may be desired.

The table or support C, as shown, is a simple leaf fastened securely tothe ball. Any equivalent form 1 will furnish a general support for thearticles may be employed.'- At each end, on the inside, is an auxiliaryL, projecting and adjustable inward towardthe file by means of `abearing, M, rest-ing under the main leaf, provided with a transverseslot v, running overa set screw w. i

It is common in saw filing machines to give the file a reciprocatingmovement, and to perform the requi action withoutparticularmanipulation; but such arrangements are for a particular use,and are not adapte the general' and promiscuous business of tiling. Itis our special design to apply power to the purpose, an make the machinecapable of performing many diiferent oiiices.

To this end the file carriage is made to reciprocate rapidly, and thearticle to be led is presented to it on `:he table or support C. It willbe seen that either the carriage or table, or both,are'made to adjustnearer mgether or further apart by means of the flanges. f, bolts g, andslots a and are also made to incline longi- ;udinally or laterally, orto simply turn to any angle, horizontally, by means of the ball andsocket joints, as ndicated by red lines, fig. 2. This adapts the machineto almost a universal use. Thus, any` angle, bevel, or nclination maybegiven to theedge of they article being filed, or. any ntchmay be made inthe same, as the lecessities of Athe case may require.

lInaddition-to this, the auxiliary leaves L L are made adjustable in andout, as indicated in red lines,.ig. 1, hus enabling the articles placedthereon to be. brought in contactzwith the edge of the file.

The clamps I and screws r notonly'enable the le to be readily attachedand detached, but also to be adjusted ligher or lower at pleasure, asindicated by red lines, iig. 2.

The machine above described is adaptedto accomplish lmuch of the lingdone in large manufactories and hops,v where the same is simply plainwork; and, as itis accomplished by the application'of power,"a greataving in labor and expenseis eected. In these respects it differs fromsaw -iling machines or any other for the urpose of ling that wehave-ever seen.

We do not claim a reciprocating file, nor clamp holder, when they areadjustable, either orboth, to specially equired positions, as in sawfiling machines; but

1. What we claim as our invention, and desire to secure byLettersPatent, is the table C, adjustable in the maner described, incombination with the reciprocating file K, substantially as and for thepurpose -herein'speciiiei 2. The combination of two ball and socketjoints E LD, adjustable in position, one bearing a file carriage nd theother a table, or support, for the articles led, for the purposehereinpsetforth.

3. The combinationof 'the lateral auxiliary leaves L, with the table C,and file carriage H, foithe purpose f presenting the article to be filedtothe, edge of the iile, substantially as specifled.

4. The arrangement of the machine as a whole, consisting of the carriageframe -13,-the'iile carriage H, 1e table C, provided with -thelateral'leaves L, and the universal joints D E, constructed asdescribed, the whole perating substantially as herein setforth.

5. The combination of the cam m with the file carriage H, which isprovided with a reacting forca-.lso that s returns will economize timeand power, as'set forth.
